Application led June 11, 1927. Serial No. 198,026.

My invention relates to improvements in laundry devices and more particularly to that type of laundry apparatus designed for the semi-drying of Washed fabrics and garments preliminary to ironing and airing.

The object of my invention is to provide a centrifugal drier of the kind described which will permit of a more convenient and expeditious handling of laundrie-d goods.

A more particular object of my invention is to provide an.. improved apparatus of simple construction by means of which garments and fabrics after washing may be placed in a hopper, given a preliminary drying and then quickly dumped by the novel means forming a part of the present invention.

Another object of my invention is to providenovel means for handling garments and fabrics in a mannerto obviatev damaging or tearing same.

Other objects and advantages of the methods and means employed will appearv more fully hereinafter as set forth in the detailed description, reference being had to the accompanying drawing in which Figure 1 is a side elevation of my device partly in cross section showing the apparatus as it appears in actual operation.

Figure 2 is a vertical cross section of an embodiment of my invention.

Figure 3 is a cross section taken on line 3-3 of Figure 2. Y

Figure 4 is a plan view of t-he turn table as shown with the hopper removed and with a part broken away to show thel roller bearing.

Figure 5 is a detailed 'view of a driving clutch member.

Referring more particularly to the drawings in which similar` characters of references apply to like parts in the several views, 10 is an outlet valve of a container 11, having a lid 11', an inclosing wall 12 and a bottom 18. 14 is a. hopper received by container 11,-the hopper having draining perforation's 15, and compartments 17 and 18, formed by web 19, having a socket 20, adapted to receive the squared shoulder 21, lof a divided shaft 22 having an upper section 22 provided with a female clutch part 23, and a lower section 24 having a male clutch member 25', forming the complete clutch 25. Keyed to an intermediate'part 26, of the upper section 22 of the shaft 22, is a turn table having the ange 50', rotatably supported on the container bottom 13, by roller bearings 27.

The hopper 14, is closed at its lower end by folding, collapsible bottoms 51 and 52 connected to weblf) by hinges 28 and 25),-bottoms 51 and 52 being adapted to be held in normal position as shown in Figure L', by spring-impelled latches 30, registering in sockets 31 in the walls of the hopper 14. The hopper 14, while removably mounted, seats firmly on the shaft 22. The latches are released when desired, by the latch strings 32 which are united in the draw cord 33 after passing over the trunnions 34. The shaft 22 is also provided with a stufling box 35 and a thrust bearing 36, supported by bracket 37, bolted to rigid lioor extension 38. A collar 39 on the upper section 22 of the shaft. 22. iinpingiiig against bracket 37, serves lo prevent vertical shifting of the shaft On an overhead track 40, a member 4l, provided witli guide wheels 42, running on track 40, and provided also with supporting truunions 43 serves as a crane to lift and convey the hopper 14. A-belt 44, is additionally provided to be connected to the male clutch mein` ber as a further "source of optional power,

when desired.

The mode of operation of my device will now be obvious upon referring to the drawing and is briefly as follows Garments and fabrics, after the' preliminary wet. wash, are placed in the hopper li which is either directly in the container 1l or optionally conveyed to the container by the overhead traveling crane. Upon revolution of the shaft 22 through the intermediary of the expansion centrifugal clutch which binds both members of the clutch into fritcional engagement under normal speeds of the power 'shaft 22-the hopper is revolved and the water in the garments and fabrics, following the well known centrifugal process, flies tangentially from the peripery of the hopper through the perforations 15 and thence to the Hoor bottom of the container, where it is drained by means of the outlet valve 10. The double compartment in the hopper provides a ready means of dividing the fabrics and gar* ments into two different groups, if desired, for their better subsequent classification.

By the method and means shown, I have been able to etlect a substantial saving of time and labor in handling the wet wash of a laundry. ln the provisions of the novel hinged bott-Onis and latches for the dumping of the wash, I have alsobeen able to prevent catching of the fabrics on projecting points, theree by, avoiding much consequent damage to garments 17 and 18 may be individually dumped by pulling its'respeetive vlatch string 3i). in the manner indicated. It is, of course, understood that the drying of garments and fabrics in the hopper is carried only to a point best suited for subsequent ironing.

ihile I have shown and described a preferred embodiment ofthe various parts, it will be understood thatthe device is susceptible of modification without departing from the essential feature of, or sacrificing any of the advantages thereof, and, hence, I do not wish to be understood as limiting myself to the precise arrangement and formation of thc several parts-herein shown but desire to avail myself of such variations and modifications as fairly fall within the scope of the appended claims.

What I claim as new, and desire to secure by Letters Patent is:

1. A centrifugal drier comprising a container, a revolving hopper securedvto a web having-a socket adapted yto receive a shaft, said web being secured to the inner periphery of said hopper, a plurality of bottoms hingi edly' secured to said web, and means. to re leasingly lock said bottoms to said container whereby thc'bottonis may be selectively, separately and simultaneously supported and collapsed as desired. 2. A centrifugal mounted on revolvable shaft, a central com-v partment dividing web in said hopper, a pair of folding bottoms hinged to the web, and

drier comprising a con-v tainer, a hopper removably and operatively means to support and collapse said bottoms when desired.

3. A centrifugal drier comprising a cont-ainer, a hopper having compartments and a circumferential wall, said hopper being removably and operatively mounted on a revolvable shaft, a collapsible bottom hingedly connected to a central web secured to said circumferential wall, said hopper relcasingly supported against the circumferential wall, and means wherebyv the hopper with material contained therein, may be raised, manipulated and dumped while inv a vertical position.

- A centrifugal drier comprising a container, a power1 actuated shaft in said container, a removable hopper provided with a web having a socket adapted to register with said shaft, a bottomy centrally divided and` hinged 'to the web, and means on the bottoms to releasingly support and collapse said bottoms, when desired.

5. A centrifugal drier, comprising an outer container, a hopper in said container having a central compartment dividing web, and a collapsible bottom consisting of two fiaps hingedly connected to the central web, means in said web providing a socket adapted to removably seat on a power actuated shaft, means integral with the hopper to drain liquid from said hopper While revolving, and means to releasably support and dump when desired said collapsible bottom.

G. A centrifugal drier, comprising an outer container, an inner revolvable hopper including a circumferentially perforated inclosing wall, a center web secured to and dividing said hopper into two compartments, means in said web to receive and be actuated by a power operated shaft, and releasable means to support and dump material selectively in either compartments and simultaneously in both compartments, substantially as described'.

In testimony whereof I have signed my name to this specification.l
